Re: Porting C programs written for AIX

Hi Jim, 

It is difficult to help you without understanding what the program is 
supposed to do... 

 char *newformat[30];   is a valid C declaration as a pointer to an array 
of pointer to char... 

I am not a C expert and I have no experience with AIX C,, but I would 
agree with the compiler ... from my view it is not valid to use strcpy() 
between a pointer to a pointer and a pointer to a character. 

Paul

this is our include section (which I am seeing referenced with err 
CZM0280)

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sqludf.h>
#include "veapi.h"
#include "vefpe.h"
